Summary: This gene encodes a protein that belongs to the serpin (serine protease inhibitor) family. The encoded protein is an alpha-globulin with corticosteroid-binding properties. This is the major transport protein for glucorticoids and progestins in the blood of most vertebrates. The gene localizes to a chromosomal region containing several closely related serine protease inhibitors. [provided by RefSeq, Sep 2015]

What's a GeneRIF?

CBG is involved in the gender differences observed in corticosteroids circulating levels and plays a role in the local regulation of corticosteroids availability in organs like lung.
Title: New Roles for Corticosteroid Binding Globulin and Opposite Expression Profiles in Lung and Liver.
the same gene encodes brain and liver corticosteroid-binding globulin
Title: Adrenal steroids in the brain: role of the intrinsic expression of corticosteroid-binding globulin (CBG) in the stress response.
Data suggest fine control interaction between plasma CBG upregulation and stress-induced corticosterone (CORT) release in mouse model of psychological stress; CBG appears to function in maintaining dynamic equilibrium between CBG-bound/-unbound CORT.
Title: Corticosteroid-binding globulin contributes to the neuroendocrine phenotype of mice selected for extremes in stress reactivity.
Sequencing analysis showed that Cbg cDNA obtained from the mouse hypothalamus was homologous to Cbg cDNA obtained from the liver.
Title: Intrinsic expression of transcortin in neural cells of the mouse brain: a histochemical and molecular study.
Cbg-/- mice, unlike controls, remain insensitive to stress applied before memory retrieval. Furthermore, under stress conditions, we observed a blunted surge of corticosterone (CORT) in plasma and no free CORT rise in the hippocampus of Cbg-/-.
Title: Critical role of plasma corticosteroid-binding-globulin during stress to promote glucocorticoid delivery to the brain: impact on memory retrieval.
study describes functional hyporesponsiveness and aldosterone resistance in distal colon of CBG(-/-) mice; steroid actions require an intrinsic but unknown function of CBG, which allows the sufficient supply of the hormone/s to the target tissue
Title: Impaired aldosterone responsiveness in corticosteroid binding globulin deficient mice.
Critical role of plasma Cbg in providing an adequate endocrine and behavioral response to stress.
Title: Plasma transcortin influences endocrine and behavioral stress responses in mice.
These data suggest an active role for CBG in bioavailability, local delivery, and/or cellular signal transduction of glucocorticoids that extends beyond a function as a mere cargo transporter.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
